LTE; General Packet Radio Service (GPRS) enhancements for Evolved Universal Terrestrial Radio Access Network (E-UTRAN) access (V11.3.0; 3GPP TS 23.401 version 11.3.0 Release 11)
The present document defines the Stage 2 service description for the Evolved 3GPP Packet Switched Domain - also known as the Evolved Packet System (EPS) in this document. The Evolved 3GPP Packet Switched Domain provides IP connectivity using the Evolved Universal Terrestrial Radio Access Network (E-UTRAN). The specification covers both roaming and non-roaming scenarios and covers all aspects@ including mobility between EUTRAN and pre-E-UTRAN 3GPP radio access technologies@ policy control and charging@ and authentication. The Radio Access Network functionality is documented only to the extent necessary to describe the overall system. TS 36.300 [5] contains the overall description of the Evolved Universal Terrestrial Radio Access (E-UTRA) and Evolved Universal Terrestrial Radio Access Network (E-UTRAN). ITU-T Recommendation I.130 [3] describes a three-stage method for characterisation of telecommunication services@ and ITU-T Recommendation Q.65 [4] defines Stage 2 of the method. TS 23.402 [2] is a companion specification to this specification.
